The recent “WannaCry” ransomware outbreak in May infected over 230,000 computers in 150 countries. It was spread by exploiting a known Windows vulnerability. It then encrypted all PC files and requested ransom in Bitcoin to unlock all files.
Exosphere’s defense in depth is able to defeat such an attack:
- PC Healthcheck
When PC Healtheck is in place, the operating system is regularly patched, thereby WannaCry and other ransomware attempting to exploit known vulnerabilities will fail to spread.
- Anti-Malware
Advanced anti-malware will neutralize the threat as soon as it is discovered in the wild.
- Anti-Ransomware
Exosphere’s anti-ransomware capability implements a data firewall that denies WannaCry (or any other unknown application) from overwriting user data.
- Backup
Even if all else has failed and the ransomware was able to corrupt user files, these will easy to restore from the Exosphere backup.
